I think there are a lot of discussions about pgs testing on here. Just like among scientists, I don’t think there’s consensus. In theory, it should pretty much ensure a healthy pregnancy. In reality, it seems to improve the odds but definitely no guarantees. There are people who have implanted embryos that were said to be abnormal that turned into perfectly healthy babies. But there are others who didn’t have any luck till they transferred a pgs tested embryo.
My personal take - if you have a lot of fertilized embryos and you want a better shot at transferring an embryo with the highest odds of success AND you have egg quality/sperm quality issues, I would do it. That is, if money isn’t an issue. If money’s a problem, you might be better off putting that money towards more cycles. That’s just my two cents.
I do otherwise think that clinics are business. Businesses exist to maximize profit. Think very carefully about what is really necessary in your case. Otherwise the temptation will always be there to try everything. Clinics know someone desperate to have a child will do almost anything to improve the odds of success.
